To convert kilometers to miles, you can use the conversion factor 1 mile = 1.61 kilometers.
To find out how many miles Timmy’s van travels per gallon, you can use the following formula:
\[ \text{Miles} = \frac{\text{Kilometers}}{1.61} \]
Given that Timmy’s van travels 30 kilometers per gallon:
\[ \text{Miles} = \frac{30 \text{ km}}{1.61} \approx 18.634 \]
Now, rounding to the nearest tenth:
\[ 18.634 \approx 18.6 \]
Thus, the van travels approximately 18.6 miles per gallon.
The correct response is: 18.6
